How can I get the {parameters} from the patterns of handlers in Middlewares?

Hi

I have a scenario of performing actions on users :

Main Code :

<?php
use SergiX44\Nutgram\Nutgram;
use App\Commands\DeleteUserCommand;
use App\Commands\AddToFreindsCommand;
use App\Commands\BlockUserCommand;

$bot = new Nutgram('TOKEN');

$bot->onCallbackQueryData('delete_user:{id}', DeleteUserCommand::class);
$bot->onCallbackQueryData('add_to_friends:{id}', AddToFreindsCommand::class);
$bot->onCallbackQueryData('bloc_kuser:{id}', BlockUserCommand::class);
// ...

$bot->run();

DeleteUserCommand :

<?php

namespace App\Commands;

use App\Models\User;
use SergiX44\Nutgram\Nutgram;

class DeleteUserCommand
{
    public function __invoke(Nutgram $bot, $id)
    {
        $user = User::find($id);
        if (! $user) {
            throw new Exception("User with id {$id} not found! ...");
        }
        // do delete
        $bot->sendMessage("User with id {$id} deleted.");
    }
}

AddUserToFreindsCommand :

<?php

namespace App\Commands;

use App\Models\User;
use SergiX44\Nutgram\Nutgram;

class AddToFreindsCommand
{
    public function __invoke(Nutgram $bot, $id)
    {
        $user = User::find($id);
        if (! $user) {
            throw new Exception("User with id {$id} not found! ...");
        }
        // do add
        $bot->sendMessage("User with id {$id} added to freinds list.");
    }
}

BlockUserCommand :

<?php

namespace App\Commands;

use App\Models\User;
use SergiX44\Nutgram\Nutgram;

class BlockUserCommand
{
    public function __invoke(Nutgram $bot, $id)
    {
        $user = User::find($id);
        if (! $user) {
            throw new Exception("User with id {$id} not found! ...");
        }
        // do block
        $bot->sendMessage("User with id {$id} blocked.");
    }
}

If you pay attention, this code is always repeated in the above classes:

$user = User::find($id);
if (! $user) {
    throw new Exception("User with id {$id} not found! ...");
}

Okay, I'm thinking of defining a middleware as follows to check the presence of a user.
And finally, my code will change as follows :

Main Code :

<?php
use SergiX44\Nutgram\Nutgram;
use App\Commands\DeleteUserCommand;
use App\Commands\AddToFreindsCommand;
use App\Commands\BlockUserCommand;

$bot = new Nutgram('TOKEN');

$bot->onCallbackQueryData('delete_user:{id}', DeleteUserCommand::class)->middleware(CheckUserExistenceMiddleware::class);
$bot->onCallbackQueryData('add_to_friends:{id}', AddToFreindsCommand::class)->middleware(CheckUserExistenceMiddleware::class);
$bot->onCallbackQueryData('bloc_kuser:{id}', BlockUserCommand::class)->middleware(CheckUserExistenceMiddleware::class);
// ...

$bot->run();

CheckUserExistenceMiddleware :

<?php

namespace App\Middlewares;

use App\Models\User;
use SergiX44\Nutgram\Nutgram;

class CheckUserExistenceMiddleware
{
   // In Nutgram, it is not possible to send the parameters that we have defined in the handlers... Here, the $id parameter is defined only for example.
    public function __invoke(Nutgram $bot, $next, $id)
    {
        $user = User::find($id);
        if (! $user) {
            throw new Exception("User with id {$id} not found! ...");
        }
        // do stuff
        $next($bot);
    }
}

But there is a problem. how can i pass {id} that i'm defined in the first parameter of onCallbackQueryData (i mean delete_user:{id}, ... ) to CheckUserExistenceMiddleware ?

Please help me.
Thank you

Just do this:

class CheckUserExistenceMiddleware
{
  public function __invoke(Nutgram $bot, $next)
  {
      [$action, $userID] = explode(':', $bot->callbackQuery()->data);

      $user = User::find($userID);
      if (! $user) {
          throw new Exception("User with id {$id} not found! ...");
      }
      // do stuff
      $next($bot);
  }
}
